' The present invention relates to anew and improved mechanism forslotting and scoring sheet material in the making of box blanks. I e

" I In a machine oft-his general type, it has been customaryto provide aseries of pairs of co-acting 'rotary members between which the sheet isadvanced to score it along a series of fold lines, and a second seriesof pairs of co-acting rotary members, between which the sheet isadvanced to slot it at one or both ends of each of the score'or creaselines to separate adjacent portions which may be later folded to formthe ends or end flaps of the box. A machine of this general typeisdisclosed in the Langston Patent 1,7 69,883, dated July 1, 1930.

In said patent, there is provided interengaging parts between thescoring and slotting mechanisms, so that unisonalaxial movement thereofis effected, and so that the position of each slot will bear afixed'relationship to the position of its associated crease line in thesheet. Sometimes, however, it is desirable to change the relativeposition of each slot with respect to the position of its related creaseline in the sheet. I For instance, when the slots are positioned inexact center line registry with their related score lines, the

edges of the outside flaps will project flush with or possibly slightlybeyond the side surface of the resultant box when folded into shape.Thus in shipment or handling, the edges of the flap is often caught andpulled up to loosen the flap or give the box the appearance of beingdamaged. j

The present invention provides a' mecha nism for easily and quicklyefiiecting independent axialignovement of the scoring and slottingmechanism, whereby the postion. of the slot can be selectively adjustedwith respect to the position of its related crease or score line in thesheet. I a

The present invention still further provides easily accessible adjustingmembers for effecting. the independent axial movement of the scoring andslotting mechanisms.

The invention also includes certain other new and important features ofconstruction and combinations will be particularly pointed out intheappended claims,-the invention itself, as to its objects andadvantages; the mode'of its operation and the manner of its organizationmay be better understood by referring to the following description ofone specific form tak'en in connection with the accompanying draw- 'ingsforming a partthereof; in which 7 Fig. 1 is a vertical section throughaportion of a machineembodying the invention and showingone set of thescoring and slotting units. v i Fig. 2 isa front elevation showing theslotting Inechanisin with its associated adjusting means. i i Fig. 3i'sa front elevation showing the scoring wheel and its associated adjustingmeans.

The machine can be equally adapted to form the box blank shown in Fig. 7with slots 10a disposed in olfset relationship with respect to, theirassociated score lines 11a. 'A box constructed from a blank of this typewill form a box shown in Fig. 8 with the sides of the outside flaps wellwithin the side contour of said box. I I

For scoring or creasing the blank to form the score lines 11 or 11a, anysuitable scoring mechanism known in the art may be employed. One form ofmechanism which may be used for that purpose includes a plain surfacedroller 13, splined to a shaft 14 and having cooperating therewith ascoring Wheel 15. This-wheel15 has a scoring periphery 16 of V orotherappropriate form andis splined to a shaft 17 for rotation therewith andaxial A number of these scoring units are positioned along theirrespective shafts andthe distance between successive units determined inaccordance with vthe desired size and proportions of the box to beformed.

The slotting mechanism may be of the usual well-known construction, andin the form shown in the drawings includes an upper slotting head 20,splined to a shaft 21, and having mounted thereon a pair of blades 22for making the side cuts of the slot and a nib part 23 formaking the endcuts. These blades '22 are relatively adjustable circumferentially so asto effect any selective length of the box between the score lines 12., Alower slotting head 24 hasa groove 25 for the engagement of said bladesand is splined to a shaft 26 for axial movement therealong. All fourshafts 14, 17, 21 and 26 are rotated in synchronism by any suitablemeans such as that shown in the prior Langston patentabove referredto.

In order to move the scoring wheel 15 axially, there is provided a fixedbar 30, having connected thereto a rack 31, which meshes with a pinion32. This pinion 32 is journaled between two slider members 33 and 34which embrace the bar 30 and which are connected togetherto travel alongsaid bar. One end of the shaft of the pinion 32 has secured thereto acollar 35 and the other end projects beyond the slider 34 and forms ahead 36 which is shaped for the reception of a suitable turning tool.

Connected to the slider member 34 and abutting the sides of the lowerscoring member are plates 37. These plates are advantageously providedwith linings 38 of suitable material for obviating metallic clashingbetween said plates and the scoring member. By means of thisarrangement, when it is desired to axially'move the scoring wheel 15,the pinion 32 is turned in response to the mani'pulation of the head 36so that the sliders 33 and 34 are moved along the bar 30. This movementof the sliders effects the movement of the plates 37 and thecorresponding movement of the scoring wheel 15 along its shaft 17.

In order to clamp the slider members in a fixed position after thedesired adjustment has been effected, ascrew member 38 is provideclpassing through both sliders 33 and 34 o a rack 44 which engages apinion 45 looselymounted on the slider 41. This pinion 45, has its shaftextending beyond said slider in substantially parallel relationship withthe shaft of the pinion 32 and terminating ina head 46 shaped to receivethe said turning tool.

Connected to the sliders of the slotting mechanism and engaging bothsides of the header 24 are plates 47 having a lining 48 similar to thelining 38. By turning the pinion, the whole slider mechanism will beaxially displaced, and the slotting head 24 will be carried therewith bythe engagement of the plates 47. If the upper slotting head be stoppedwith its blade in the groove of the lower head, both heads will be movedsimultaneously.

VVeprovide means for indicating from the setting of machine the amountofofiset between the score, lines and the slots. This includes a pointerconnected for movement on either the-scoring or slotting mechanism andregistration marks operating with said point- .er and positioned formovementwith the other mechanism. In the'specific form'of 41 is providedwith a calibration 50. Indicatively cooperating with said calibration isa pointer 51 oifset from one end of a shank 52 which is threaded orotherwise connected to the slider member 34. This pointer 51 has a markwhich registers with the calibration 50. Vhen it is desired to constructa blank as shown in Fig. 5, the mark on the pointer 51 is made toregister with the zero mark on the calibration 50. Vhen it is desired todisplace the slots in any selective position with respect to theirrelated creases, the slotting mechanism is moved the desired distancefrom either side of the zero mark as indicated by the pointer 51.

It should be noted that the two adjusting 7 heads 36 and 46 and theclamping head 39 justing head 36 is turned to axially move the Lesseescoring wheel 15 along its shaft 16 in accordance with the desired shapeof the box to be.

formed. This scoring wheel 15 is then clamped in position against axialmovement by means of the screw member and the slotting head 24 axiallymoved as already described to eifect the desired alinement or offsletbetween the crease line and its associated s ot.
